Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: shared: fix use-after-free bug when adding shared proxies
The GPIO lookup table can stay alive for longer than the kobject whose name string's address we're assigning to lookup->dev_id. Fix a potential UAF by duplicating the string.
